Garmin Boat Switch gives you full digital control of your boat’s electrical systems directly from your Garmin GPSMAP® or ECHOMAP™ chartplotter. With this all-in-one solution, you can easily control lights, pumps, horns, ventilation, accessories, and much more—without the need for traditional switches, relays, and fuses.
The system supports up to 20 circuits and provides intelligent protection, monitoring, and fault management via an intuitive, software-based user interface. You can customize control panels, name functions, add icons, and get a clear overview of the status of all systems on board.
Garmin Boat Switch also makes it possible to monitor up to four tanks (e.g., fuel, freshwater, wastewater, greywater, or livewell) with built-in tank calibration. Additionally, you can track battery voltage, bilge pump activity, and other critical system data—directly on the chartplotter.
The device is designed for easy retrofitting in existing boats and comes with color-coded cables and installation instructions. The result is a modern, secure, and fully integrated boating experience—with fewer components, less wiring, and much greater control.
